The mother and brother of Academy Award-winning actress Jennifer Hudson were found shot to death in the mother's Chicago home on Friday.

The Chicago Fire Department confirmed that two adults were found dead at 70th Street and Yale Avenue. The Chicago Police Department also confirmed two people were found shot to death at the residence and said it was "being investigated as a homicide." But police did not release the identities of the victims or other details.

The entertainment website TMZ, citing a neighbor, said Hudson's brother Jason also was found dead. A cousin who lived nearby discovered the bodies, TMZ said. The Tribune, quoting police, said the killings may be linked to a domestic disturbance.

Authorities issued an Amber Alert for 7-year-old Julian King, and were seeking a 1994 white Chevrolet Suburban. The child was the grandson of the female victim, Patterson said, and Bond added the boy could also be a relative of Hudson.

The alert said the child was possibly abducted, and accompanied by a man — considered armed and dangerous who was a suspect in the double homicide investigation. The two could also be in a teal or green Chrysler Concord with a temporary license plate, a left front headlight hanging out and scratches on the left side of the vehicle, police said.
